This invention relatespto advertising devices, and has for an object the provision of a novel advertising ydevice. which includes an MV, endless curtain so arranged within asuitable housing, that it is adapted to be continuously moved across a window through which advertising matter carried by the curtain, may be observed. The advertising device of the present invention, is an improvement over that of my copending application, Serial No,y

348,486, filed March 20, 1929.

Y Another object is the provision of an advertising device of the general character described, in which the endless curtain carrying 175 the yadvertising matter, is interchangeable with others, so that the device may be varied at willY to convey to'anobserver, whatever intelligence mayy be desired.. a

e A further object is to provide an advertising device ofthis general character, which 1s of van exceedinglyfsimple nature, being `composed of'relatively few and simple parts, and which is of such a nature that the screen carfrying-the Vadvertising matter, vmay vbe 'removed andreplaced' by another, with the ut-Y most ease.v Y Thisinvention possessesother objects and advantageous features, some of which, with those enumerated, will be set forth in the fol- 30 lowing description of the inventions particu` lar embodiment which: is illustrated in the drawings accompanying and" forming a part lofthe specication. Y

yReferring to the drawings: .f

. In terms of broadl'inclusion, the advertisingdevice ofthe present invention comprises ahousing having a window in awall'thereof, andadapted to removablyreceive a framework upon whicha plurality of rollers are journalled. An endless curtainis carried by F ig..2 is a transverse, vertical, medial sec' 1930. Serial N0. 472,034.

the rollers, suitable driving means being associated therewith so as'to cause continued motion of the curtain upon the rollers, whereby that portion of the curtain which is visible through the window of the housing, is continuously changed. The curtain is provided with translucent areas arranged in the form of letters or other graphic representations wherby information may be conveyed to an observer; and a light source is provided behind that portionof the curtain which is visible through the window so as to increase the visbility of the translucent areas. An important feature of the invention lies in the fact that the frame may be removed from the interior of the housing, and the curtain removed from the rollers to permit its being replaced byanother carrying different advertising matter, thus permitting the use of the machine to advertise different commodities at different times.

Speciiically describing that embodiment of the invention which at present appears to be the most practical, my improved advertising device comprises a housing 6 which is preferably more or less ornamental in eX- ternal appearance, and in the front wall 7 of which a preferably relatively large aperture 8 is provided, forming a window through which a curtain may be observed. The yback wall l1 of the housing 6, is removably attached by means of a plurality of screws 12 which extend through the back adjacent its edges, `and are threaded into a flange 13 formedby bending inwards the after edges of the top 14 and side walls 16.

Removal of the back 11 permits access to a frame 17 comprising a base 18 resting loosely upon thebottom`19 of the housing 6, and a pair of spaced sides 21 and 22. Theside 21 is rigidly'secured to the base 18, at or adjacent one end thereof, and rises vertically therefrom.A However, the side 22 is not directlyfconn'ected to the base 18instead, it is provided with a brace 23-removably attached to the lower end ofthe side 22 by preferably a plurality of screw/S24, and to the base 18 adjacent y the other end thereof, -bya screw. 26. `Vhen the brace 23 is removed, theV side 22is adapted/to be supported'by meansof-a re- Hector 27 which is rigidly attached at one end tothe side 2l, and at the other end toy the side 22. This reflector issubstantially triangular in cross-sectional configuration, and comprises preferably fiat-upper and lower sides 28l and 29 respectively,having their end edges turned-outwards to form iangesl and 32 respectively, Awhereby they mayzberigidly attached to the upright sides 2l and 2 2 ofthe frame `17. These sides 28 and 29 of the reflector, are arranged-in angular .relationship with each other, divergingtowardthen1 forwardvedges; and' their inner 'faces arehighly polished or are coated with-soniejhighly rel flective material so as to increase the etliciency of preferablyla i plurality-of electriclight bulbs mou-nted in sockets Y34; `which are carried by theareflector A27V adjacent the convergent afteredges of the sidesz28 .and 29 thereof. Thereflector 27 vis arranged sothat Y i-tregisters with the window8 in .the .front Wall'37.of .the housing 6. Y

are 'arranged'in vertical alignmentadj acent the-frontofthe frame 17 ,and the other rollers 36 and 39fadjacent vk'the after edge of the frame.
